The Environmental Protection Agency (EPA) is proposing to approve State Implementation Plan (SIP) revisions submitted by the State of Wyoming on May 28, 2015 and November 6, 2015. The amendments update the version of the Code of Federal Regulations (CFR) incorporated by reference into the rules of the State of Wyoming for Chapter 2, Section 12; Chapter 3, General Emission Standards, Section 9; and Chapter 6, Prevention of Significant Deterioration, Section 4. The May 28, 2015 submittal updates a citation to a Federal Register article (i.e., Federal Register notice) under the definition of "tpy CO<INF>2</INF> equivalent emissions (CO<INF>2</INF>e)," and lists a new minor source baseline date for fine particulate. The State also proposes to update the primary air quality standards for particulate matter (PM<INF>2.5</INF>) to reflect federal updates that went into effect in January 2013. The updated primary PM<INF>2.5</INF> standard is 12 micrograms per cubic meter ([micro]g/m\3\) annual arithmetic mean concentration, which is lowered from its previous level of 15 [micro]g/ m\3\. The EPA is also proposing approval of portions of the State's February 6, 2014 2008 ozone National Ambient Air Quality Standards (NAAQS) infrastructure certification regarding prevention of significant deterioration (PSD) and the good neighbor provision. The EPA is not taking action on the Chapter 6, Permitting Requirements, Section 14 portion of the May 24, 2012 submittal because it has been superseded by a November 6, 2015 submittal (81 FR 35271). The EPA is not taking action on a May 24, 2012 submittal or a March 8, 2013 submittal because they have been superseded by the May 28, 2015 submittal.
